AD8625ARZ

Overview

The AD8625ARZ is a quad precision JFET input operational amplifier from Analog Devices. It supports single-supply operation from 5 V to 26 V and dual-supply operation from ±2.5 V to ±13 V. Key electrical specifications include a maximum offset voltage of 0.5 mV, a maximum input bias current of 1 pA, and a gain bandwidth product of 5 MHz. The device features rail-to-rail output capability and unity gain stability.

Feature Summary

• Precision JFET input stage providing extremely low input bias current
• True single-supply operation with rail-to-rail output swing
• Unity gain stable design without phase reversal near supply rails
• Low power consumption suitable for battery-powered applications

Applications

• Photodiode transimpedance amplification
• ATE reference level drivers
• Battery management systems
• Remote sensor signal conditioning including automotive sensors
• Precision active filters

Procurement Notes

Verify the specific package suffix against the datasheet ordering guide to ensure correct pinout and physical dimensions. Confirm that the component meets RoHS compliance requirements for your manufacturing process. Check absolute maximum ratings to ensure operating conditions remain within specified limits for long-term reliability.

Selection Notes

Select this component when picoampere-level input currents are critical for minimizing errors in high-impedance circuits. The rail-to-rail output allows for maximum dynamic range in single-supply systems. Ensure the application does not require shutdown functionality or higher bandwidth than the 5 MHz specification provides.

Part Context

This part belongs to the AD862x family of precision amplifiers, which also includes the dual-channel AD8626 and single-channel AD8627 variants. All members share identical electrical characteristics but differ in channel count and available package options such as SOIC, TSSOP, MSOP, and SC70.

Replacement Considerations

Direct functional replacements within the same family include the AD8626 and AD8627, provided the channel count matches the circuit design requirements. Verify pin compatibility if substituting between different package types within the series.
